The luminescence of the Sb3+ ion in Ln(PO3)3 (Ln = Sc, Lu, Y, Gd, La)

Design and Synthesis of CdWO4:Sb3+ Phosphor Based on sp Energy Level Regularities of Sb3+ Ion

“…It is shown that the four chemical parameters, coordination number, fractional covalence, bond volume polarizability, and presented charge, are factors influencing the positions of excitation bands of Sb 3+ ion in host lattices. In particular, the conclusion is to some extent consistent with the previous observations by Blasse et al . Covalence and coordination number are usually considered to be two main factors that influencing the energy levels of ns 2 ion in crystals.…”

“…Comparatively, although there are two crystallographic sites for Sr 2+ ion in Sr 3 (PO 4 ) 2 , the luminescence properties of the Sb 3+ ‐doped Sr 3 (PO 4 ) 2 crystal are similar with that of Sb 3+ ‐doped orthophosphates . The luminescence of Sb 3+ in trimeta‐phosphates Ln (PO 3 ) 3 ( Ln = Sc, Lu, Y, Gd) was also reported and the photoluminescence spectra and decay time measurements were given to show the differences in luminescence characteristics of four Sb 3+ centers . The detailed semiempirical molecular orbital model was used to interpret the excitation and emission spectra of Sb 3+ in calcium halophosphates, as well as Ca(II) site substitution .…”

“…From the previous work about the spectroscopy of Sb 3+ discussed above, it can be found that crystallographic structure, coordination number, and the charge compensation effect, can influence the luminescence of Sb 3+ ion in host lattices. However, there is still a lot of research needed in this area to understand the quantitative correlations between the host environment and the optical properties of Sb 3+ ion.…”

“…Sb 3+ ion has been used as an activator in a variety of hosts such as halides, sulfides, selenides, borates, phosphates, halophosphates, calcium halophoshphates, and oxygen chlorides . Research had been performed about the luminescence of Sb 3+ ion in inorganic host to get more insight into the way how the crystal environment influence the observed luminescence properties of Sb 3+ ion . In this approach, it was focused on the influence of the lattice structure on the luminescence of Sb 3+ ion.…”

Luminescent properties of Yb-doped monoclinic yttrium polyphosphates

“…Some works report results for the luminescence of Bi 3+ [8] and Sb 3+ [9] in Ln(PO 3 ) 3 (Ln ¼ Sc, Y, Gd, Lu) and of Tb 3+ in monoclinic Gd(PO 3 ) 3 [10].…”
